Ring traveler



J. W. DUB OIS RING TRAVELER Nov. 14, 1967 Filed Oct. 7, 1966 INVENTORdosEPH W Dusors 2 ATTORNEY United States Patent ABSTRACT OF THEDISCLQSURE A traveler for the rings of spinning or twisting frameshaving a pair of vertically aligned and integrally formed bow elementsthe lower of which serves to guide said traveler while moving about saidring and the upper for maintaining the yarn guided thereby entrappedduring the entire cycle of spinning or twisting.

This invention pertains to travelers for ring spinning or twistingframes and more particularly to improvements in the conformation of thetravelers for maintaining control of the yarn during a dolf or duringany period of machine stoppage.

During the period of a deft, prior to a start-up, the height of the ringrail is often changed and may cause a slackening of the previously spunyarn. The yarn extending through the traveler to the base of the spindlehas had twist applied so that when the tension is removed, it will tendto untwist in a curling, loop forming motion. This activity oftenunthreads the traveler, causing endsdown which result in additionalmanual labor for rethreading the travelers. Any increase in thedown-time of the machine is to be avoided if possible as the unit costof production is similarly increased. The instant invention is directedtoward eliminating the problem of traveler unthreading.

It is a general object of the invention to provide a ring traveler whichwill, in any unsupported position on the ring flange, entrap the yarn.

It is a further object of the invention to provide a traveler having twocircumferential lock points for entrapping the yarn therebetween.

It is another object of the invention to provide a traveler having aring flange encircling bow and a vertically disposed yarn bow.

It is a still further object of the invention to provide a travelerwhich may be applied easily to the ring flange.

These and other objects will become apparent as further details aredisclosed. The invention will be described by reference to a specificembodiment as illustrated in the accompanying figures of drawing,wherein:

FIG. 1 is an elevation of a bobbin in a spinning ring with the yarndrawn through the traveler in preparation for start-up;

FIG. 2 is a vertical section of a portion of the ring with the travelerin a spinning position; and

FIG. 3 is similar to FIG. 2 showing the traveler in an unsupportedposition.

Now referring to the drawings, a spindle and bobbin 21 are adapted to bedriven by a continuous tape 22 in a known manner. The bobbin 21 projectsthrough a ring rail 23 and a ring 24 which has a smooth upper horizontalflange 25. The ring may also have a similar lower flange 26 for use in areversed position to double the period of use. A strand of yarn 27extends downwardly from a supplying source, as for example draftingrolls (not shown). The yarn 27 is threaded through a traveler, generallydesignated 28, and inwardly of the ring 24 to the base of the spindle 20where a few loops 29 firmly secure the end.

The traveler 28 has an upper bow portion 30, which in 3am? Patented Nov.1 1967 the preferred embodiment takes a generally elliptical form;however, this may also be circular or angular formation. The bow portion30 at its base continues into two shoulders 31 and 32 of equal lengthand spaced apart from each other a distance considerably less than thewidth of the flange 25. The traveler 28 may be made from flat wire stockor of any other suitable material and may be of unitary construction asshown.

Vertically aligned with the bow 30 are two outwardly arcuated horns 33and 34 extending downwardly from the shoulders 31 and 32, respectively.As shown in FIG. 2, the horns 33 and 34 may be integral with the bow 30by being bent reversely upon the shoulders 31 and 32 and arcuatedgenerally elliptically. The horns 33 and 34 terminate in opposing ends35 and 36 separated from each other sufficiently to lock about theflange 25. Application of the traveler 28 is made by springing the ends35 and 36 apart as they are pressed over the flange 25. There is lesspossibility of travel breakage at application because of the doublespring action of the combination of the how 30 and the horns 33 and 34.The conformation of the traveler is that of a lower flange-encirclingportion in tangential relationship with an upper yarn-controllingportion.

In operation the yarn 27 is threaded through the bow 30 to the base ofthe spindle 25), then as the rail 23 is raised and the spindle rotatedthe yarn will build up upon the bobbin. Previous to the dotf a few moreloops are allowed to form upon the spindle to lock the yarn while thebobbin is removed. An empty bobbin is applied and the rail is raised inpreparation for starting up. This allows the yarn to slacken and twistinto loops which may work free from the traveler unless restrained insome manner. In the instant invention, slackening of the yarn will dropthe traveler to the flange 25 with both shoulders 31 and 32 in contacttherewith. No matter at what angle the traveler may drop both shoulderswill contact the flange and entrap the filling within the bow 30. Thetraveler herein provides constant control of the yarn during any periodof machine shut-down and greatly reduces the manual operation connectedwith ends-down.

While one embodiment of the invention has been disclosed, it is to beunderstood that the inventive concept may be carried out in a number ofways. This invention is, therefore, not to be limited to the precisedetails described, but is intended to embrace all variations andmodifications thereof falling within the spirit of the invention and thescope of the claims.

-I claim:

1. A traveler for a ring having a horizontally disposed flange whichincludes a bow, said bow terminating in a pair of opposed shouldersdisposed in spaced and aligned relation, and an arcuated horn memberextending downwardly from each of said shoulders in the same plane assaid bow for encircling said flange.

2. A traveler as set forth in claim 1 wherein the horn members areintegrally formed in vertically aligned relation with said shoulders andbow and are separately disposed in general elliptical formation with theends thereof having a distance therebetween less than the width of saidflange.
